Hi Liza,
From what I can tell is that you get the one bumper sticker for free and if you want extra you have to pay for it.
It still says on the botton of the first page “Due to overwhelming interest in the DSCC bumper sticker, we will begin shipping in 2 to 4 weeks. Thank you for your patience as we process your request.”

I will send them an email and see if this is expired and let you know asap.
